VESSEL AND CLOSURE FOR HYDRAULIC AGITATION OF DENTURES AND THE LIKE This application is a continuation in part of my copending application Ser. No. 81 1,510 filed Mar. 28, 1969, now abandoned.

Although this vessel and closure can be employed for the hydraulically agitated cleaning of various types of articles, it is dentures which are particularly adapted to be cleaned therein. There are of course various special preparations in which dentures can be soaked, but there is in fact no better method than to wash them regularly in scalding water. Consequently, an assurance of avoiding obnoxious odors and in order to promote good hygiene, persons wearing dentures diligently wash them in hot water, with or without cleansers, and in steaming and/or scalding water if at all possible. However, there is a limit to the degree of heat which a persons hands and fingers can withstand while manipulating the dentures in the hot water, and this presents a serious limitation in the results of such a washing operation. Open-topped vessels and glasses or jars are not the answer, since an unconfined hydraulic wash will flood the dentures out of a vessel, glasses are fragile, and uncontrolled hydraulics cannot be most effective. Therefore, it is na object of this invention to provide a vessel and closure combination that most effectively controls hydraulic flow, to direct its entry into and to direct its discharge from the vessel while creating and confining the turbulent flow of fluid and agitation of the denture and/or articles within the confines of said vessel.

It is also an object of this invention to provide a vessel, closed as above referred to, which has holding means that captures it in working position for receiving a pressurized jet of water, all without capsizing and without requiring a person to hold the vessel in position. With the present invention, the vessel and its closure are aligned with the jet of hot and/or scalding water eminating from a faucet, and left there, preferably within the confines of a washbasin or the like, to receive the jet of water and to redirect the water so as to create the agitating action sought for, and all to the end that the dentures float about and are thoroughly washed from every single angle reaching into every crevice and interstice.

The various objects and features of this invention will be fully understood from the following detailed description of the typical preferred form and application thereof, throughout which description reference is made to the accompanying drawings, in which:

FIG. 1 is a sectional view taken through a typical sink, showing the articles of the present invention in use and in elevation;

FIG. 2 is an enlarged sectional view of the assembled structure of the present invention as it is shown in FIG. 1;

H0. 3 is a plan view taken as indicated by line 3-3 on FIG. 1; and

FIG. 4 is a fragmentary sectional view taken as indicated by line 4-4 on FIG. 2.

Dentures, partialor full, are characterized by their sets of teeth fixed in a frame adapted to fit with a persons jaw through engagement of the gums, and/or with remaining natu ral teeth. During the course of a day's use, the fluids of the mouth and accumulations of food particles are caught up in the crevices and interstices of the dentures and become odorous. Therefore, periodical cleaning of such dentures is necessary and among the best methods of cleaning is washing with scalding water. Various preparations can be used before and/or after such a washing, but in any case use of very hot water is most effective and especially when agitation thereofis employed. Consequently, the present invention provides a vessel V and a closure C for hydraulic agitation of dentures D and the like, wherein a jet of very hot water can be usefully employed in the form that it is usually delivered from a water faucet F. As shown, a jet of water is delivered in a substantially vertical and downward direction from the faucet F in a pencillike stream. Such a jet of water 10 is common and almost universally employed in connection with domestic washbasins B in lavatories and the like. Such basins are usually provided with porcelain interiors or the equivalent and with a smooth hard-surfaced bowl. A drain 11 is provided at the bottom for carrying away used water.

In accordance with theinvention a vessel V and closure C combination is provided and usefully employed by aligning it with the jet of water 10 and with the dentures D or the like accommodated therein for agitation and cleansing by a washing action that is most effective. The vessel V and closure C are made of moldable material such as a plastic that impedes heat transfer. There are many such plastics which are easily molded and which do not efficiently transfer heat, which are also durable and conducive to cleanliness. It is such material that the vessel V and closure C are made of, preferably a plastic that is bendable for manipulating the two elements V and C into and out of coupled engagement.

The vessel V is an upstanding open-topped vessel having a bottom 15 and sidewalls 16. The bottom is horizontally disposed while the walls 16 are vertically disposed extending upward from the outer periphery of the bottom. As shown, the bottom is round in which casethe walls 16 form a cylinder. The upper end of the vessel is completely open and has an attaching rim 17 which in practice is a radially enlarged bead 18. Also, in carrying out the invention, the bottom 15 is filleted at 19 where it joins the walls 16, and said fillet turns radially inward and into a cone-shaped center 20 that projects convexly upward establishing a concaved bottom. 1

The closure C is a planar element that covers the open upper end of the vessel V and is preferably a domed disc form having a periphery with a depending flange 22 to mate with the bead 18 for attachment. The said bead l8 and flange 22 have overlapped engagement that is forcibly fitted for coupled engagement of the closure C and supporting vessel V. In accordance with the invention, the closure C is apertured at 30 and 35 for the separated reception and discharge of fluid, and nozzle means 40 is associated with the receptive aperture 30 and directs fluid to swirl through the vessel V in a predetermined manner. In practice, a flow pattern is established whereby the entry of high-velocity fluid swirls downwardly in a helical path adjacent the cylindrical wall 16 and is turned at the bottom of the vessel to swirl upwardly in a continuing helical path at the center of the vessel and is then discharged. The flow is continuous and impeded by the presence of articles within the vessel, and all of which creates turbulence and assures effective cleaning, with the apertures 30 and 35 positioned and shown as now described:

Aperture 30 is the fluid-receiving port and it is located in the marginal portion of the closure C immediately adjacent the wall 16 of the vessel. Aperture 35 is the fluid-discharging port and it is located in and occupies the central portion of the closure C. Both apertures 30 and 35 are ports of ample area, the aperture 30 being of somewhat larger area than the diameter of the jet of water 10. This is, the jet of water 10 enters the aperture 30 with clearance. However, the lower velocity water leaving the vessel V is in a flooded condition and simply swirls upwardly through the aperture 35 to flow laterally in omnidirections.

A feature of the invention is the nozzle means 40 which determines and directs the predetermined flow pattern of the fluid that is forced into the vessel V and is spent therein and then discharged for disposal as waste. The nozzle means 40 is adapted to receive a high-velocity jet of water 10, to collect it and to redirect it to the useful purpose of agitation within the vessel V. Normally, a jet of water 10 is disposed vertically or substantially so, and its velocity is downward. Therefore, the nozzle means 40 opens upwardly for the reception of the jet water 10 and is an upwardly flared cone that has a funnel shape and a corresponding collective function. However, the axis a of the cone-shaped nozzle means 40 is angularly or helically disposed and tangent to a radius point spaced immediately inward from the wall 16 of the vessel V. Although the pitch of the helix can vary, a 45 angle is most practical and is shown. The opening 41 of said nozzle means is restricted as compared with the mouth 42 of the aperture 30 and functions to direct fluid circumferentialiy within the confines of the cylindrical wall 16. Consequently, the jet of water revolves and/or swirls toward the bottom of the vessel where it is turned radially inward by the fillet at 19 and upwardly by the conical center 20, whereupon the vessel V is filled with swirling water that rises to the top and discharges through the central aperture 40 and without interferring with the incoming jet of water 10.

Securement means B is provided for the attachment of the vessel V to the smooth surface ofa porcelain bowl or the like, and as shown in the drawing, the means B advantageously employs the bottom concaved contour of the vessel V. in the event that the plastic material of the vessel is sufficiently pliable or supple then the perimeter of the bottom is feather edged as indicated at 25, and so that its suppleness conforms to the contours of the basin. in the event that the vessel material is excessively stiff, then the securement means B is a separate element of sufficiently pliable material, such as an elastomer, attached to the bottom 15 and with the lip 25 projecting radially and downwardly at its perimeter, as shown.

When in operation as hereinabove described, the dentures D are captured within the confines of the vessel V and its attached closure C, the dentures being a greater bulk than that permitted to pass through the aperture 40. The rolling effect of the downwardly swirling water at the periphery acting in opposition to the upwardly swirling water at the center lifts and tumbles the dentures, and a continuation of this effect en sures a thorough cleaning, especially when jetting highvelocity scalding water into the vessel as directed by the nozzle means 40. Upon completion of sufficient cleaning, the plastic vessel V is manipulatable, due to the low heat-retaining character of the plastic material, and without danger of scalding ones hands or fingers. it is to be understood that the vessel V and fluid directive closure C therefor is applicable to a wide range of sizes and configurations, namely to conduct cleaning processes and the like as may be required of articles susceptible to processing by agitation in a moving fluid.
